Abstract

A contact device for an electrical switch, and an electrical switch are disclosed. In an embodiment the contact device includes a first connection element, a second connection element, a movable contact bridge, at least two magnets configured to quench arcs which arise during a switching of the electrical switch, wherein the magnets are configured to generate a magnetic field in a first region which comprises at least one first contact region and one second contact region, in which, when the electrical switch is in a closed switching position, the first connection element and the second connection element are in contact with the contact bridge and at least one deflection element configured to distort the magnetic field such that a first arc when formed between the first connection element and the contact bridge, and a second arc when formed between the second connection element and the contact bridge, are forced into different directions, pointing away from each other.
